对产后 1～ 6个月的乳母及其婴儿分别进行了乳汁中钙、铁、锌含量测定和婴儿身高、体重测量。结果显示 ,母乳中钙、铁含量与国内资料接近 ,而锌含量偏低 ;乳汁中的铁和锌含量随喂养时间延长而逐渐下降 ;钙含量在四个月前无明显变化 ,五个月后呈下降趋势。相关统计结果表明 ,乳汁中的钙、铁与婴儿的身高、体重无显著相关 (P >0 0 5 ) ,锌与婴儿身高、体重呈显著正相关 (P <0 0 1 )。
Milk, calcium, iron and zinc in breast milk and infant’s height and body weight were measured in 1 to 6 months after delivery. The results showed that the contents of calcium and iron in breast milk were similar to those in China, but the content of zinc was low. The content of iron and zinc in milk decreased gradually with the prolongation of feeding time. The content of calcium did not change significantly in four months and five months later Showing a downward trend. The statistical results showed that there was no significant correlation between calcium and iron in breast milk and the height and weight of infants (P> 0.05). There was a significant positive correlation between zinc and infant height and weight (P <0.01).
